RED OAK WATER SUPPLY is one of 91 community water systems in Iowa in the 3,301 to 10,000 people size category, serving 5,596 people from groundwater.

As of August 1, 2026, its federal record holds 30 entries between 1992 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 30, 29 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
